performance

问题 Context I'm learning how to code in javascript consistently, readably and maintainably. I found nothing about the order of declaration of variables and functions. Example: var example = { A: function() { var a, b, c; }, B: function() { var a, b, c; }, C: function() { var a, b, c; } } Questions Alphabetically is the best one ? Is that the order can improve the speed of code execution ? 回答1: I use jslint to check the code quality. It can be integrated with Visual Studio and a lot of other stuff

问题 I'm doing [very] intense numerical calculations related to physics using solvers written in C++. A single run can take up to few hours on my PC, and one need dozens. I've found that it is possible to significantly (2-5x) decrease the time almost without losing accuracy, if one tabulates smooth functions and uses tabulated values instead. The code below illustrates what do I mean: main.h #pragma once #include <iostream> #include <chrono> #include <math.h> #include <memory> typedef double(*fnc)
